摘要:

为促进可再生能源的最大化利用并兼顾不同用户的经济效益,研究了协调多方主体利益的综合能源站的优化运行策略。以不同主体的能量流动关系为基础,考虑分时电价和不确定性的影响构建了电、热、冷负荷的需求响应模型,在引入碳交易机制的基础上,建立了综合能源站运行净收益、新能源消纳率和用户满意度最大化的3个目标。针对所建多目标模型的高维非线性特征,通过引入惩罚函数和多项式变异策略对多目标分解算法进行改进,以提升算法求解的全局搜索能力,同时避免陷入局部最优解。仿真算例表明:所提优化模型使得综合能源站净收益、新能源消纳率和用户满意度分别提高9.39%、8.18%和5.81%。

Abstract:

To promote the utilization of renewable resources and improve economic interests of different subjects, here proposes a method for optimization operation strategy of Integrated Energy Station that coordinating different subject interests. Firstly, some demand response models for various loads were established by considering load uncertainty and time series electricity prices, based on the analysis of energy flow relationship of different subjects and the impact of demand response. Secondly, through introduction of carbon trading, her constructed three objective functions with the maximum net profit of Integrated Energy Station, the new energy consumption rate and the user's satisfaction. Thirdly, according to high dimensional and nonlinear features of the proposed objective, an improved multi-objective decomposition evolution algorithm is proposed by employing penalty function and polynomial mutation strategy. The simulation experiment shows that the proposed optimization model can increase the net revenue of the integrated energy station by 9.39%, the consumption rate of new energy by 8.18%and user satisfaction by 5.81%.

Key words: integrated energy station, decompose multi-objective evolutionary algorithms, load response, distributed generator
